Return value by lambda in Java

Question

Till now I manage to find all answers I need but this one confusing me. Let\'s say we have example code:

public class Animal {
   private String species;
   priv         


        

Answer 1

Yes, when specifying only a single statement, its value is automatically returned from the lambda.

Then, since Runnable is a Functional Interface, it can be defined as a lambda. The return type is void, so any return value inside the lambda will be ignored.
